INSULATOR PIN Filed June 4, 1926 Patented Nov. 3, 1931 UNITED STATES PATENT oFFIcE KENT A. HAWLEY, or BALTIM E, iuanynnnn, nssienon T men INsULA'roR CORPORATION, or BALTIMORE, nAnYLAnn, A CORPORATION, or MARYLAND INSULATOR PIN Application filed June 4,

The invention relates to insulator supporting pins and mountings therefor. The primary ob'ect of the invention, gen.- erally stated, is to provide the combination with a supporting pin, of a base andasaddle member therefor whereby. mounting may be readily eflected upon-a curvedor froofed typeofcross arm. a 4 a :Y is It is well known that the insulator maybe secured upon the pin prior to the mounting of the latter upon a crosslarm, or that the pin ma be mounted upon the cross arm first, su sequently to which the insulatoris screwed down tightly, or otherwise fastened, the groove in the insulator being permitted to come as it will. It then becomes necessary to turn, the pin and the base thereof, asa unit, to bring the insulator groovein the same direction as'the transmission wire or conductor so as to receiveand hold the same, There is no diflicu'lty where the. pin is used in connection withacrossarm of the fiat top type, but in caseswhere cross arms of the curved or froofed variety are used, there is provided a saddle member which is curved to fit the cross arm and which supports the present invention has for a more specific object the provision of a saddle member ofthe curved type for use on roofed cross arms, but having a flat bearing surface constituting a seat. for the base of the pin to support the latter adequately and make it possible to effect positive securing and prevent any cantingof the pin Without there being any necessity for the employment of any washers or other extra parts. I

Another object of the invention is, to provide a saddlemember carrying means operatively engaging and coacting with; the base of the pin for holding it; against relative displacement in a longitudinal directioniwhile permitting rotary movement to bring the 1926. Serial no. 113,744.

groove of the insulator to the proper position; a

A still more specific objectof the inventlOIlllS toprovide a pin and mounting in which the siddle member is formed with up struck lugs extending over the peripheral portion of the pin base. vi

'An additional object of'the'invention is to provide an insulator pin and mounting meansithereforwhich will be simple and inexpensive to manufacture and assemble,easy to use, positive in action, efiicient and durable in service, and a general improvement in the art. i

:Withthe above and other-objects and advantages in view the invention preferably consists in the .details of vconstruction and the arrangement and combination of parts to be hereinafter more fully described and claimed, and illustrated in the ing drawings in which: a

Figurell is a view partly in side elevation and partly in-vertical section illustrating the construction, and i V a Figure 2 is a horizontal section through the pin showing a plan view ofthe base and saddle member v Referring more particularly to the drawings, the numeral 1 designates a pin which may be of any desired length and which is here shown as having a tapered portion 2 terminating in a reduced extension 3 adapted to pass through a suitable hole in a cross arm, not shown, this extension being threaded for engagement ofvthe usualsecuring nut thereon. Thepin assembly further includes a base 4 with a tapered socket 5 therein within which the tapered portion 2 of the pin has a driven fit.

The numeral '6 designates'a saddle member here represented as curved transversely to fit conformingly upon a "roofed type of cross arm. The central portion of the saddle member is pressed, stamped'orotherwise formed with a central upstandingportion7 which has aflat, plane or horizontal top surface 8 constituting a seat for the base 4:. As another feature, the saddle member is providedwith "retaining means engaging over the peripheral portion of the base, this reaccompanytaining means being disclosed, in the present instance, as consisting of any desired number of upstruck lugs 9 which extend outwardly of the edge of the base and which have their ends bent over thereonto as shown at 10.

In the use of the device it will be seen that it is applied in the same manner as other pins and after it is in position it is a simple matter to engage a suitable wrench upon the pin and turn it sufiiciently to bring the insulator in such position that the groove therein will extend in the same direction as the line wire for the reception thereof, subsequently to which the nut provided on the threaded extension is tightened to hold the parts against displacement. It will be observed that the saddle member cannot be detached from the pin without removing it together with the base, the parts being consequently held against separation during handling at any stage or in shipment. Naturally as the entire device is initially assembled as'indicated there will be no multiplicityof parts to be handled individually and put together when use of the pin is desired, this resulting in a saving in time and labor when making installations.

From the foregoing description and a study of the drawings it will be apparent that I have thus provided a very simply constructed and inexpensive insulator supporting pin structure which may be produced readily from bar stock out to any desired length, the amount of machining being reduced to the minimum so that the construction and assembly may be effected with the fewest possible operations. It is really believed that the advantages and benefits derived from the employment of such a structure will be readily apparent to one skilled in the art without further explanation.

lVhile I have shown and described the preferred embodiment of the invention and certain details of construction and arrangement, it should be understood that the disclosure is merely an exemplification of the principles involved and that the right is reserved to make such changes and variations as will widen the field of utility of the invention provided such modifications constitute no departure from the spirit of the invention or the scope of the claims hereunto appended.

Having thus described the invention, I claim: 1. In an insulator support, the combination of a saddle member adapted for engagement upon a cross arm, a pin equipped with a base and having a threaded extension passing through the saddle member, the saddle member having a seat portion for the base, and mean-s independent of the pin on the saddle member for retaining the base there- 2. In an insulator support, the combination of a saddle member adapted for engagement upon a cross arm, a pm equipped with a base and having a threaded extension passing through the saddle member, the saddle member having a seat portion for the base, and means independent of the pin on the saddle member preventing relative longitudinal movement of the base and saddle member, while permitting relative rotary movement thereof.

3. In an insulator support, the combination of a saddle member adapted for e11- gagement upon a cross arm, a pin having a separate base cooperating therewith and having a threaded extension passing through the saddle member, the saddle member having a seat portion for the base, and means on the saddle member embracing the base for preventing relative longitudinal movement of the base and saddle member while permitting relative rotary movement.

4. In an insulator supporting structure, a saddle member having a'seat portion, a pin carrying a base engaged upon the seat portion, the pin having an extension passing through the saddle member, and retaining means on the saddle member engaging over the periphery of the base for preventing relative longitudinal movement of the base and saddle member, the base and pin being rotatable with respect to the saddle member and formed of separable parts.

5. In an insulator supporting structure, a saddle member of curved form adapted for engagement upon a roofed type of cross arm and having an upstanding fiat seat portion, a pin extending through said seat portion and carrying a base rotatably engaged upon the seat portion, and elements on the seat portion engaging the peripheral portion of the base, the pin having a tapered portion, and the base having a correspondingly tapered socket. V

6. In an insulator supporting structure, a saddle member of curved form adapted for engagement upon a roofed type of cross arm and having an upstanding fiat seat portion, a pin extending through said seat portion and carrying a base rotatably engagedupon the seat portion, and elements on the seat portion engaging the peripheral portion of the base, said elements being formed as clips struck up from the saddle member.

7 In an insulator support, the combination of a saddle member adapted for engagement upon a cross arm, a pin having a separate base cooperating therewith and having .a threaded extension passing through the saddle member, the saddle member having a seat portion for the base, and upstanding means on the saddle member for retaining the base thereon.

8. In an insulator support, the combination of a saddle member adapted for engagement upon a cross arm, a pin having a sepa rate base cooperating therewith and having an extension passing through the saddle member, said extension being threaded from a point beyond the saddle member, the saddle member having a seat portion for the base, and means on the saddle member outwardly of and engaging the base for preventing relative longitudinal movement of the base and saddle member While permitting relative rotary movement thereof.

In testimony whereof I aflix my signature.
